• HOW DO YOU O«DER ONE? Cannibalized pares are asked foe on the same DA Form 2765 (Request for Issue or Turn-in) used for a normal supply request. . with a difference, of course. The difference is chat you r supply support wants you to include enough description for the "ca n" point type to understand exactly which part you want. Aleer all, they're the ones who have to hit the boneyard on a recon patrol for your part. YOU USE THE INFO HERE TO FILL OUT DA FORM 2765 ... SO YOUR SUPPLY SUPPORT PEOPLE WILL KNOW WHAT PART YOU WANT.

WORKS FOR STOCKED ITEMS, TOO Every now and then you can justify goi ng to the "can" poine for a regu lar stocked item. That happens whenever you r supply support sends you a supply status card tell ing you it's OK to pick up a short-s upply or oue-of-st ock item loca lly-or that you r required delivery date for chat item is goi ng to be longer than the maximum time allowed for thac icem's Priority-and you need jc bad.

A worn Out part without an FSN or maybe any number is like an R & R returnee who's lost his ID card. Both will need a little extra effoct to explain what they really areand where they belong. Let that GI do his own worrying, and let's concentrate on that helpless part that can't do for itself. That part needs something like this suggested form to help your supporting

supply unic find a replacement. Suppon's authority and guide for this type of supply operation is para 3~20.1 in Ch 11 to AR 725·50. That's the reason this paragraph is referenced on the form shown here, which a lot of commands are using as a local guide.

ANY INFO YOU CAN OFFER ABOUT AN ITEM HElPS YOUR SUPPLY SUPPORT PEOPLE AND IMPROVES THEIR CHANelO OF SATISFYING YOUR SUPPLY DEMANDS ... BY CANNIBAliZATION, FABRICATION .•. OR LOCAL PURCHASIO. HERE'S A FORM LY-----r THAT WILL HIOLP YOU.

If none of these local supply sources work, this same information becomes even more valuable. Support will then use it to help make out an exception daca type of requisition. This means that supply .transaction card will be processed by hand instead of by machine. And, since it doesn't have to face a machine, a justification statement wrapped around the requisition card with a rubber band won't interfere with anything as it's moved up the supply ladder.

WORK WITII SUPPORT This approach should be worked out with your direct support unit (DSU) to be completely successful- because your unit doesn't have all the information that's needed. However, it's up to your unit to provide as much information as possible from the log book copy of DA Form 2408- 7 for that end item ... and whatever identification you can find in the equipment -20P manual. And som~ne in your outfit who's familiar with it should eyeball the actual equipment in order to describe that particular part's location, measure its dimensions, draw a sk-etch, take a picture, tell what it's made from, what it docs and how it operates. Your DSU then adds whatever it can from its -34P or -35P for that equipment, gives your unit permission to install that part and explains what happened to its attempts to cannibali ze, fabricate or local purchase that pact on the first go· round. This is all for the benefit of the supply types at GS (general support) and depot.

can nibalization is the only road to follow as a supply source for non-supply parts replacement on the M38, M38Al, .-l---~"=c:...:.:.:.::c:.:::........__A~ MI5I 114-ton and M715. M725 5/4con trucks. That's spelled out by Appendix B to TB 750-98-23 (Dec 68)_

This is the best route for quick action on an item normally considered a no-no in the supply system because it's not stocked. has no FSN or Part Number, has a long equ ipment life, is hard co identify, doesn't belong CO a higher assembly ... or a combination of the above.

Dear Windy,

We got gigged for not haying heat shield FSN ted 'he No. J hanger booring. Is it really necessory?

15~iO-7'57.:;';;Z;~~ SP6 C. W. W.

Dear Specialist C. W. W., Yes indeed! The shield protects the bearing from engine heat. \.X1ithout it the bearing would be damaged because the grease won't hold up under increased temperatures. The shield goes on B Model, SIN 6413902 thru SIN 64-14100 and on C Model, SIN 64-14101 thru 66-15245. Check with support and you'll find the shield is attached to the fireshield with the 8 bolts and washers listed in Fig 112 of TM 55_1520-21O-35P-2 (Sep 68).

1=-.;;;;;;;;

Dear What do you think about using a larger washer on the Huey (UH-rDJ connecting tube between the stabilizer bar and damper? As' see it, the washer under the head of the aHaching bolts is too small. A loose tube and bearing could ride over the washer and bolt-control of the bird would be lost. MAJ J. H. P. Any suggestions?

Dear Major J.H.P., Yes, indeed. Safety washers, pIN 206.010·324-1, FSN 5310- 131 -2667, can he used under each holt head on pIN 204-010·925series connecting tubes for the UH-I B, D and H models.

Very important point! The XM28EJ takes different left- and right-hand weapons controllers and g un drive motors . Instead of getting 2 firing rates by use of a resistor - as used on the XM28 - the X M28 El uses a dua l-voltage motor. So, even though the weapon controllers look alik e, you ca n't swap them no- how.

Can't stress enough that you shou ld NEVER puc the XM28 speed controllers and/or machine gu n drives on the XM28El, or vice versa. Just remember w hat could happen : If the pilot or g unner should put his weapon select sw itch on BOTH, the Minnie and the 40-M M cou ld both fire

Machine Gun Drive Gimmick \Vith the Western Gear motor you don't have to be stuck by that RH and LH label. You 45)20'5 can convert from right-

hand

to

lefthand drive-or vice versa-easy. To make a

switch, do this:

sure the lever on the sighting station is in the up position-engaged. This'll keep the turret from depressing more than 35 degrees and banging the weapo ns into th e ground , which lets dirt and sa nd iDeo the barrels. The blocked bar-

TURRET CHUTIIG - Never operate the turret with either the ammo container or the gun end of the chuting disconnecred. Otherwise you'll tear up the limit switches, chuting and wiring. Remember, the chutes muSt be either completely installed or completely removed before you operate the turret! This goes for b()(h Minnies and grenade launchers, too.

Inslollolion IRemovol Reminders Pretty tricky business installing Minnies and grenade launchers and all their stuff on this system, what with all the com binations possible. Notch these cues in your noggin and you'll come Out ahead:

AMMO DRIVE SHAFTS - Run 'em through the chute scparator- bu t make sure there's enough slack on the turret side to keep the shaft from being stretch· ed and cut when the turret moves. Keep a balance between turret and ammo bay. Too much slack can fou l and get cut.

you get the right·size pins in the right places and insta lled the right way. Frinstance, the release pin that holds the front end of the delink ing feeder to the gun must always be heads up. 17

AMMO COMPARTMENTS - Never forget to unplug both electrical connectors on the rear of the containers before you slide the 7.62- andlor 40-MM ammo containers out or you'll damage the plugs and the wiring and short out your system. Watch these wires after they're unplugged, too. Don't set boxes or your big feet on 'em. And eyeball 'em constantly for cutS and bent pins in the connectors.

gether with nylon lacing cord everywhere you can to keep 'em out of troubie. And make sure the 40-MM flex drive shaft is held by ny Ion webbing provided for this purpose.

Be cotron-pick in ' sure you 've got firing pin 65F10057 in your XM28/xM28EI 's M134 G un or you're setti ng up a jam session. No other wi ll do! This pin's a component of parts kit, pin and spring set FSN 1005-052-9558 (PiN 5910873). The pin's not stocked or issued separatcly. You can tell it by the "V" wi th a dot in it on the top rear of the firing pin, right behind the elongated slot. The slot itself is longer than on othcr Minnie firing pins so the tang of the p in can contact the rear of the bolt assembly. This keeps the pin from vibrating into the extracted position when the 40-MIKE-M IKE's being fired. MI34 LOAOING TIP -Never forget to doublecheck the loaded chute for looseness or tightness after you're finished loading. If you ca n't budge the ammo the width of one round fore a nd aft with your finger, or if you can move it the wid th of almost 2 rounds, make w ith the fixes in para 2-18b(10)(a) and (b) of your

XMIZ9 Grenade Launcher Herc'ce some of the main trouble spots co look for when you steip it for

cleaning and lubing:

DRUM ASSEMBLY -Inter· nal cam paths badly worn.

FIRING PIN STRIKER - Tip badly burred ..

Grooved pin missing; slide badly burred.

CARTRIDGE FEED ACTUA· TOR - Feed lever worn, cracked; feed and follower gear teeth worn, busted; feed arm roller worn.

YOKE GUIDE - Bent, dent· ed, twisted.

That feed arm roller can be a tfouble-maker. By the book (Table 3·4), you should replace it after 10,000 rounds, but it could wear before thac. If you find it Aatsided, put a new onc in promo. For sure, it's a lot easier to replace this roller than to replace the feed cam . .. which is what you'd have to do if the

roller gets shot. 'Cause if the roller's shot the cam will wear away and slow down the firing and finally affect the timing. 19

Best bet: Put plenty of LSA-T on the cam track every time you clean your weapon. T his'll get you lots more mileage on the roller . LSA-T comes in an

Every time you' re fiel d-stripping and re-assembling your launcher, be mighty sure to heed the special inst ructions in pa ra 3-2 l of you r -12 T M. You'll save mucho time and sweat and maybe a miss ion or two. F'rinstance, w hen you're putting the drive assembly back together, you've got to set the firing pin tolera nce exactly right before you install the drive assembly ... and th is can be a neat trick. H ere's how it goes :

20

MISSIONS HAVE FAI~ED WHEN THE 40-MM DRIVE' SHAFT WAS INS TA~~ED WRONG- REMEMBER- ,HE' SHAn IS LIKE YOUR AUTOMOBI~E SPEEDOME'TER CAB~E - IT TURNS INSIDE' THE CASING.

XMIZ9 Drive Shaft

,---=......-,---,--------,

It's extra important to make sure the gun drive shaft is attached exactly right at both ends-the drive end down below and the turret end up above. Otherwise your 40-MIKE-MIKE will be just excess baggage on the Cobra. Connie says it's something like threading a needle in the dark to get the top end right, since you can't see what you're doing. What you have to do is to work the square end of the cable into the square hole in the gun drive motOr assembly by feeling your way. What you have to avoid is putting the square end of the cable next to the square hole. Sure, it'll slide in there and even seem to tighten up OK, but the launcher won't fiee.

Here's the way you'd do it On a iefe-mounted launcher:

21

Incidentally, new cables come equipped with a stat.shaped washer that goes on the inner cable at the turret end. A handy gadget-but not critical. If you've gOt one, use it; if not, don't sweat it, you can still do a good hand job without it. This washer's not in the supply system, so save your breath.

DYNAMIC BRAKE SWITCH ADJUST· MENT -Check this adjustment every day and a lso after borcsighting. Para 3·19a of your ·12 TM has the poop. Get the habit of eyeballing that aluminum switch cam to see that it's not bent. If it is, you may be able to straighten it out with a plastic. head hammer, but if you run into trouble with it get support to work on it. The big thing is that the

40·MM LOADING TIP - You can discourage jamming of the 40·MIKE· MIKE this way: Turn magazine in a feed direction and hand·guide first round through feed tray until engaged by feed pawl. Continue feed as you hand· rotate launcher drum to a point where the barrel JUSt starts to close over the round. Adjust ammunition belt tension by using a ratchet wrench on the shaft of the ammo drum. Then check to see if ammo can be rolled slighdy fore and aft in the chute. Ammo too tight or too loose can bind in the chute and cause malfunctions.

GUM CRADLE ASSEMBLY -

Every

time you install the XM 129 launcher, double check to see that the 4 bolts (2 top, 2 bottom) that keep the launcher in the cradle are tight. Safecy wire (.032) bolts in pairs to keep 'em tight. They do work loose, you kno~!

AMMO RESERVE PERCEIIT METER -Play it safe and set the meter on the gunner's control panel at 85 perccnc for a fuJlload of 40·MM ammo and your mission-makers will come out OK. Why nOt set it at 100 percent like for a full load of 7.62-MM ammo? Here's why: 100 percenc on the meter means 300 for 254 ... 255 ... 25b .• NOW THAT'S ONl-Y 85% OF A 300 ROUND LOAD SO SET YOUR METER AT 85"10 FOR A FULL LOAD OF 40MM ROUND. OK.
